Description

1/ I sign a file using this method

public static void signByPdfbox(
File inputPDF,
File outputPDF,
KeyStore ks,
String password)
throws IOException, UnrecoverableKeyException, KeyStoreException, NoSuchAlgorithmException, COSVisitorException, SignatureException

{ PDDocument inputDoc = PDDocument.load(inputPDF); PADESSigner signer = new PADESSigner(ks, password); signer.setSignatureName("Hello1"); signer.setSignatureReason("Why noy"); signer.setSignatureLocation("Curacao"); signer.setSignatureContactInfo("[e-mail]"); signer.signPDF(inputDoc, outputPDF); }

2/ I resign the same file using the same method and in acrobat reader I have this error : SignDict/Contents illegal data

I have googelized it, and I found only old topics for iText lib.
I have tried the same with iText 5.X, and double signatures works
